摘　　要：本文提出一个从探地雷达回波信号中重建三维物体图象的方法。该方法视图象重建为一积分变换,先根据脉冲压缩和合成孔径原理确定校函数的分解形式,再通过求解变分问题导出校函数的最优解。仿真实验表明,此核函数及重建方法是可行的。A method for reconstructing 3-D object images from a set of return signals of a subsurface radar is developed. The image reconstruction process is described as a linear integral transformation. The degenerate kernel based on the principle of pulse compression and aperture synthesis is proposed and then is solved by means of variational method. The numerical results are demonstrated to prove that the imaging method with the new kernel is feasibility.
